IMPROVEMENT IN PICTURE-EXHIBITORS.

Specification forming part of Letters Patent No. 172,328, dated January 18, 1876; application filed October 28, 1875.

To all whom it may concern:

Be it known that I, GEORGE A. LAUER, of Cincinnati, Hamilton county, State of Ohio, have invented an Improvement in Photographic Albums, of which the following is a specification:

My invention relates to a class of photographic albums in which the pictures are exhibited and secured within a stand or casein a more secure and protected manner than in the ordinary book'album and my invention consists in part of a certain construction of the case or cabinet and arrangement of glasses or lenses, whereby the best light is thrown upon the pictures, and the most complete facilities are secured for viewing them, and the pictures being secured to an endless belt, by operating which, one picture at a time will appear at a given point of view.

Figure l is a perspective View of a photoalbum or cabinet, embodying my invention. Fig. 2 .is a partial perspective view of the frame for holding the picture. Fig. 3 is a sectional view of my invention.

A is the body of the case, and B the lid, which, in connection with inclosed parts, constitutes what I am pleased to term a photographic cabinet. Fittted to revolve in the body A, at a proper distance apart, are square shafts O O", the upper shaft 0 being operative by means of handle 0, upon the outside of the case. Secured firmly around and connecting the shafts O O, is an endless belt or web, I), which will communicate the motion of shaft 0 to shaft 0, and cause them to move in unison. Secured upon this belt or web D, at regular intervals, by gluing or 0th erwise, are frame-sticks E, whose facial extent upon the belt D is exactly equal to the faces of the square, or it may be hexagonal, &c., shafts O O, and whose positions upon the belt or web D are such as to exactly oppose the faces of the square shafts O O as the belt travels over the shafts. Secured to the frame sticks E are retainingframcs 6, into which pictures may be placed. They are made of any desired material, and are secured preferably to the frame-sticks E through the medium of flanges c, which are bent down and screwed to the ends of the sticks, as seen in Fig. 2, and it is obvious that, as seen. in Fig. 3, the action of the angular shafts will bring but one picture, and bring it positively up to a given position within the vision of the operator. The lid B is titted with a pair of semicircular frames, b, which enclose or retain a semi-cylindrical glass top light, F, and two semi-circular glass side lights G, which, together, give the best light upon and facility in viewing the pictures. These lights may. at their lower edge, besunkinto the lid B,so as to strengthen their position.

Having thus described my invention, I claim- 1. A cabinet for exhibiting photographic pictures, substai'itially such as specified, when provided with a semi-cylindrical or dome-like glass top.

2. The combination of the photographic cabinet, having a semi-cylindrical or dome-like glass top and the endless belt to which the picture-lrames are secured, and by which the pictures may be successively brought into view under the glass top, substantially as specified. p

In testimony of which invention Ihereunto set my hand.

GEO. A. LAUEE.
